Synonym discussion
Sense: noun/1
Ejaculation and emission both involve the release of semen, but emission is a more clinical term that describes the internal movement of semen into the urethra, which can happen without sexual pleasure (e.g., nocturnal emission). Ejaculation specifically refers to the external expulsion that typically accompanies orgasm. Discharge is a much broader term covering any bodily fluid release — such as nasal discharge or vaginal discharge — and completely lacks sexual specificity. Climax refers to the overall peak of sexual pleasure and sensation, not the physical event of semen release. For example, a doctor might ask about 'nocturnal emission' but would diagnose 'premature ejaculation.' A person might say they 'reached climax' without necessarily mentioning ejaculation.
Etymology
The word comes from Latin 'ēiaculārī', meaning 'to shoot out' — literally 'to throw out' (from 'ex-' meaning 'out' and 'iaculārī' meaning 'to throw', related to 'iacere' meaning 'to throw'). It entered English in the early 1600s carrying the general meaning of 'a sudden utterance' (now sense 2). The physiological meaning of 'semen release' (sense 1) developed later, in the mid-1800s, as medical terminology became more precise. For most of the 20th century the physiological sense became dominant, while the original utterance sense gradually faded from ordinary use.
